Reconcile not working for other Mac users

There's really no way to help you with the information provided. You may want to consider a call with Quicken Support, where a representative can screen share your Quicken to see what you're seeing.

In general, reconciliation simply adds up all the transactions in your register and presents you with the sum; there isn't anything fancy about the math involved. But without seeing the transactions and results, it's hard to guess at where your problem is.

I will call support when they’re open. I was frustrated and it’s the weekend when they’re not availavle. Thanks

Quicken does have chat support available on weekends, but in a situation like this, I think you're better off waiting until during the week when you can call their phone support and have someone look at your Quicken screen with you in real-time.
